Three times DN300 prefabricated directly buried insulation elbow is one of the insulation pipe fittings. The insulation elbow is composed of high-density polyethylene outer pipe, polyurethane foam insulation layer and inner working steel pipe. The thermal insulation elbow is mainly used for the turning of the thermal insulation straight pipe. It is generally used in combination with the thermal insulation pipe. It is used for compensation according to the design of the thermal insulation engineering pipeline, so that the elbow can also have sufficient thermal insulation performance Thermal insulation elbow is one of the thermal insulation pipe fittings.

It is generally used in combination with thermal insulation pipe. It is used for compensation according to the design of thermal insulation engineering pipeline, so that the elbow can also have sufficient thermal insulation performance. The standard elbow angle is 30 degrees, 45 degrees, 60 degrees and 90 degrees. Insulation elbows are widely used in liquid and gas transmission pipe networks, chemical pipeline insulation projects, petroleum, chemical, central heating networks, air conditioning and ventilation pipes, and municipal engineering pipe bends.
